To all whom it may concern."

Be it known that I, FRANCIS H. RICH- ARDS, a citizen of the UnitedStates, residingA which the following is a specification.

lhis invention pertains to the relationship and organization of variouscoperative mechanisms and mechanical .devices designed to effect theselective transfer and positive location of any one of a series ofmembers or i1levices-such, for instance, as typographie impressors-toand at a given or fixed point, such members, in general, being disposednormally in various positions with respect to such given point.

A mechanical movement embodying the present improvements will comprise,ordinarily, a support or carrier, capable of angular adjustment, withwhich support there is combined mechanism for shifting said member tothe proper angular position to bring the selector'l ldeviceintoalinement with the fixed point. In cooperative relation with suolisupport and thc selective devices thereon there will be, ordinarily,suitable* and proper mechanism whereby the selected device may beshifted axially of the support, these two movements, that is, rtheadjustment through a proper-and controllable angle, and the axialmovement relatively vto the support will, as this mechanical movement isorganized, be performed consecutively, thatjs, the angular adjustmentwill be completed before. the axial shifting of the impressor or otherdevice is begun. Although tlns supportus capable, as aforesaid, of amovement aboutan'axis, I do not deem 1t essential that this movementshall bc the only oneY of which it.is capable, since the or-`'ganization may be such that there may be imparted toit acompound.movement, thatl 1s, a rbodily movement-of the member along apredetermined path, in addition to the movement which it has about vitsown axis.

Various means may be employed for effecting the rotary and longitudinalorv axial adjustment of the series of impressors'lor other devices, theorganization and construction illustrated in the presentg drawings beingone. of simple character, and it not being contemplated by suchillustration to restrict or confine'the application of the presentmechanical movement to embodiment I in such illustrated mechanisms andmechanical devices.

In these drawings, Figure 1 is mainly a. longitudinal section through akey-controlled mechanism embodying my present improvements. Fig. 2 is asimilar view of the rotary member or support embraced in the mechanism,illustrating the same in a position in which it has been adjusted to anangular position such that the selected device has een brought intovertical alinement with the point at which it is to be ultimatelylocated; and Fig. 3 is a plan view of the mechanism shown in Fig. `1.

Similar characters. of `reference designate corres ending partsinall'figures.

Altio'ugh I ilo/not propose limiting the application of/,the'presentinvention to embodiment in any particular form or constructionofmechanism, I have, for the purpose of illustration and for the sake ofconveniently representing a construction for its practical application,shown the` same as embodied 1n a `key-operated mechanism, since such anapparatus or mechanism is particularly adapted for effecting theconultimately locating the selected device at the given or fixed point.Any suitable framework ;may be provided for supporting the operativf`warts and mechanisms, such framework constituting a portion of the-main framework of the machine to which the present mechanism may beapplied, or constituting a sub-frame of such framework.

Referring to the 'construction illustrated in the drawings attached tothe present'speciiication, the framework is therein designated in ageneral way by' B, it being in this inlstance provided With,supportingposts or evs Y r,The relation between the constituent submovementsembraced in the present mechanical movement is such th at the particulardevice selected fromgamong the assemblage thereof and,occupyii'gvanormal position whichis, in general, out of botlthe verticaland horizontal planes in which `the xed 'point is located isone1 ofconsecutive motion in different directions. More specifically, thepresent mechanical movement is one whereby the seleetedldevice is rstmoved into one of the planesy of said fixedl or` given point, andsubsequently, after transfer 'trol of the various movements necessary'for Lnto i that plane, the vdevice isl shifted in that plane 'in thedirection of the fixed point and ultimately brought .to rest the'reat.InA

peint is one composed of separate and indiupon a member or support atleast capfable.Y

and combined vidual movements, the second'of which is not begun untilafter the completion of the first'. l. prefer to niountthe selectivedevices of rotation about its axis, with such inc inber, in propercooperative relation therewith, suitable mechanism, 'whereby aparticular device chosen from the plurality thereof mounted upon suchmember, may -be brouglit'into the vertical plane of the given point(assuniiiig-the axis of the member to bedisposed vertically), andsubsequently shifted relatively to. the rotary member until it reachesor is adjacent to the given point. `ln the present embodiment, therotary'member or support, designated herein in a general way by C,vis-capable only of a movement of rotation, althoughthe presentinvention is not limited in its scope of application td a membercapablc'only` lof rotation about its own axis.. For the convenientlmounting and impartation of angular or rotary movement to thismember C,

it may be mounted as shown, this mounting comprising, as illustrated intheA drawings, a shaft 2, which in this instance is disposed vertically,being mounted adjacent to its lewer end in a bearing 3 formed in theframe' B and at its upper end in a bearing 3 formed yin an overhangingbracket t fixedly secured to the upper portion of such frame. A'

shoulder 2 extending between the-'main portion of the shaft 2 and areduced portion forming the journal thereof constitutes means formaintaining the shaftin Iits proper vertical position, vthis shoulderresting upon the upper surface of the bearing 3. The 'inein' ber Cv maybe attached .to the shaft 2in any proper manner, in this case a key 2rigidly connecting the two, and the member C rotating Withfthe shaft 2.It may be premised thaty the various devices which are capable of beinglocated, se`

lectively, at the given or fixed point are disposed circumferentiallyof. the' member 0 and hence the rotary movement ofthe shaft willsu'llice to bring these circumferentiallydisposed devices into thevertical plane of the given point, here designated by x, orsubstantially so. In order to permit the rotary member to be actuatedthrough the separate angles requisite for aliningthe various devicesupon their respective selection with the `point 0c, I have, in theembodiment illustinted, represented afriction device normall operativeto continuouslyrotate the sha t and hence thc member C, but of suchconstruction as to be capable of being rendered' inoperative when aselected device has asl su ined a position vertically below such point.As set forth, a driving-pulley 5 is loosely mounted upon the shaft 2 and'driven conveniently by a belt, for instance, ,from a Vsuitable sourceof 'power (not shown). In order to connect this pulley 5 with theshaftQ, friction'washers 5', 5 on opposite sides of the hub of thepulley are shown, 'which frictionally engage'ivi th such hub and withproper opposing frict-ion surfaces. In the construction shown, thelatter friction face for the upper washer 5f is'eonstituted by the faceof a boss -6 extend-ing from the lower or base-plate of lower washer 5is' formed by the' side face members being capable of being forcedtogether 'more or .less snugly by means of a nut -8 engaging with thelower end of the for driving the shaft 2 when free so todo.

Referring now to the devices capable of selective location at the point,lthese will, of course, depend upon the character' of the apparatus towhich the movement is applied. They'are, in this case, represented inthe nature of impression devices capable of operat- 'fixed point Asbefore stated, thesedevices, designated in a general way by D, aredisposed circumferentially of 'the rotary devices being normally out ofalineinent with the point of the member C, as aforesaid, to bring achosen selective device into aliiiement with (that is, as hereorganized, vertically below) the point it, said device is -so relatedtothe member C that it may be shifted axially thereof' and so broughtinto proper relation or juxtaposition with the point'.-

According toI the preferred embodiment of the present movement, eachaxially-disposed series of'devices D will be mounted upon a properelement capable of longitudinal movement relatively to the'ineinber C.

suitable slides, designated herein by 9, each of which slides isinountedin proper guideberC to move lengthwise thereof in order toBriefly stated,- there embraced in the vpresent mechanical movement anassem the frame B, while'tlie reaction face of the.

Means are thus providedfor ad-. justingor regulating 'thefriction effective member C and also axially thereof, all of such4 Eachof' such series may, therefore,- be disposed upon' 'ways iii theperipheraltportion of the mem' of a second washer 7 these severalfriction'v ingupon-material located at the given or-v Upon the angularmovement l blageor series of selective devices disposedl bothcircumferentially-andaxiallv of a inembei, all of which are capable ofrotary movement with thc=inember, and of axial inove ment relativelythereto. In this instance there are shown eight vslides 9 (see Fig. B),although manifestly this number may be less or I'point face of theguideway formed in the member C.

As a simple and convenient mea-ns for stopping the rotation of the shaft2in such a position that the member C shall be brought to rest withthe'- slide. 9 thereon carrying the seleetedfor chosen device Dvertically below or inline' with the point'x, a key mechanism isillustrated embodying a series of levers controlling the setting ofproperly disposed sto s,

whereby a stop in roper eordinate re ation with the givenv ide 9 will,when set, effect the arrest of the shaft2 with the member C properposition, as aforesaid. I do not deem, however, a key mechanism of thischaracter as necessary or essential to a practical or operativeembodiment of the present movement, since the mechanism shown is chosenmerely as typical of the conditions requisite for causing thecessationof the roj tary movement (a motion, it will be understood, notin itself essential to the invention) vof the shaft with the member C inthe proper position, as already described. j

Referring to the particular embodiment set forth, a series of eight keysK are shown, each of which has a distinguished mark corresponding tothat slide 9 upon the member or carrier C which, when the particular keyis actuated, serves to sto the motion'of the membej` C with the shde inline with the Each key mechanism comprises a .rey K, as aforesaid,mounted at the upper end of a key-stem 7c, passing through an opening inthe front portion of the frame B, and at" its low'er end pivotallyconnected with a proper key-lever 10 fulcrumed, in this case,intermediate its ends toy a post 10 erected upon a supporting-plate orsub-frame l1 extending from side to side of the main frame J3.Controllable from each key-lever 1() is a stop-pin 12 shifted, upon theactuation of the key connected to it, radially toward the axis of theshaft 2, but normally held in its retracted position by means of aspring 13 whose vtension serves to elevate the outer end of the lever10, and hence raise the key-stem r attached thereto to its highestposition. These stop-pins 12 are preferably risposed, to insufe theirproper action, concentricall y about the axis of the shaft 2, theybeingr in this instance mounted in o enings in an annular support 14rigidly afixed to the main frame B. This support 14 has, in thisconstruction, ears 14', 14 extending toward the Aside members of themain frame, and is affixed by screws thereto in order to hold theannular support 14 in proper relation to the shaft 2.

A simple means for connectingeach lever with its proper stop-pin 12isshown in the present drawings comprising an angle-lever 15 fulerurnedintermediate its ends to the side pieces of' a bracket 16 depending.from the annular support 14v one of the arms of the angle-lever 15 beingproperly pivoted to its stop-pin, while the other thereof is connectedbya link 17 with its operating lever 10. It is plain from thisconstruction, that when a key K is depressed the inner end of theconnected key-lever 1() is elevated, causing, through the connectiondescribed, the inward movement of the stop-pin 12 operative therefrom.It will be understood that as the stop-pins 12 are disposedconcentricvally about the axis of the shaft 2, they will be disposed atvarious pointscircumferentially of the supporting ring 14; hence thevarious levers 10 for effecting their movement will, usually be ofvarious shapes in order that the inner end of each lever may be broughtinto proper relation with the anglelever 15, controlling the movement ofthe stop-pin whose setting the particular lever is desivnedmo effect.These levers will also generally in some instances be bent in onedirection or another, particularly as illustrated in Fig. 3, that theirinterference with other operative parts of the machine may be avoided.Coperative relation between the stop-'pins 12 and the shaft 2 exists inthis case through the medium of an arm 18, the hub of which is rigidlyaffixed to the shaft 2 in such a position that the plane of movement ofthe arm corresponds to the plane in which the several pins 12 aredisposed. As-

suming a pin 12 to have been projected inward by the operation of thekey K effective for its actuation, the projected pin protrudcs into thepath of the revolving stop-arm 18, and when this arm comes into contactwith it the resistance opposing the motion of the shaft 2 is sullieientto overcome the friction exerted by the rotating drivingpulley throughthe .friction-washers 5, described, and hence the motion of the shaft 2with its member C'will be arrested. ln this position, therefore, theslide 9 carrying the selected device l), which is related to the keyKidethe shaft 2 that the slide 9 in line 'with the j point. is shiftedaxiall)v with reference to i fore, shown at the side of the lever 23 aninive for positively and spendingr recess 19 formed in the lower end of4of rotation of the s iaft 2,'

For causing` at the will of theoperator it is connected to a reciprm-,atory slide-bar21 arranged toslide to and fro in brackets22, 22 projecting from the'r'ear .end oftthe 'main frame B, and being operative from a lever 23 convenientlydisposed at the side/of the inechanisinand externally of theframe B.'Ihislever 23 is aillXed-to a rock-shaft 24 journaled in properbearingsin'the side pieces of the main frai'n'e,' fromv which rockshaft,extends an arm 25 carrying at its freefend a rollerl 25 upon whichrests a lcollar-26 allixed to the reciprocatory rod 2l.- (lontactbetween the colla-rl 25S and the roller 25"is, inithis instance,nmi-itainedby a spring 27 'inserted between 22, and

.Preferably the tooth 20 is of a length suflicient to project inwardbeyond the outer edge of the guideway in the member C, in which. theslide Q is located. Hence, when the tooth is shifted out ofalinementwith the locking ringl 19 during the adjustment of a slideaxially of the member C, the latter will be locked from rotarialmovement until the slide. has again-been brought to itsnormal p0- sitionand thel tooth 20 re-aliiied with the locking` ring*- 19.
